Application Range Of Water Pump

Water pump is a mechanical device widely used in various fields. It can be used to provide fluid power and transport liquid from a low-pressure area to a high-pressure area. In the fields of industry, agriculture, construction, transportation and life, water pumps play an important role.

Water pumps are often used in industrial production processes for lubrication, cooling, water supply, and transportation of chemical liquids. Water pumps play a vital role in the petroleum, chemical, electric power, pharmaceutical and other industries. Industrial water pumps can be divided into three categories according to their working principles: blade type (power type), such as centrifugal pumps, axial flow pumps, mixed flow pumps, etc.; volumetric type, such as piston pumps, diaphragm pumps, screw pumps, vane pumps, gear pumps, etc.; other forms, such as jet pumps, air lifters, etc. Among them, centrifugal pumps often appear in production and operation activities in all walks of life because of their simple structure, small size, light weight, stable flow, easy manufacturing and portable maintenance.

Centrifugal pumps can be divided into vertical and horizontal types according to the shaft installation position; single-stage and multi-stage according to the number of impellers; single-suction and double-suction according to the impeller liquid inlet method, so as to meet the diverse production needs of various industries. However, centrifugal pumps are not suitable for all industrial conditions. They are less suitable for high-viscosity liquids and conditions with low flow and high pressure. Therefore, it is necessary to make a comprehensive choice based on industrial properties when purchasing.

According to the different requirements of the treatment medium, cast iron materials can be selected conventionally, which are more cost-effective; if it is used for corrosive media, stainless steel or brass, bronze and other more corrosion-resistant chemical pumps can be selected. If there are greater requirements for flow and head, and a single pump cannot meet the use requirements, a customized system can also be used to meet the requirements through parallel and series connection before the water pump.

Water pumps are mainly used for irrigation and drainage in the agricultural field.
Farmland irrigation generally uses water pumps to pump water from rivers and canals and transport it to farmland for irrigation, or water can be sent to mid-air for sprinkler irrigation under rated pressure to maintain the normal growth of crops. In the rainy season, the water pump in the drainage system can drain the fields and ensure the aeration of the roots of crops. It is used to drain fields in the agricultural field to prevent water accumulation from causing adverse effects on crop growth. No matter what type of water pump, as long as it is used in agricultural irrigation, it can be called an irrigation pump. When selecting a pump, it is necessary not only to consider the structure and installation method of the pump, but more importantly, to consider the actual working conditions of the farmland to make a choice. The water output of the farmland irrigation pump depends on the size of the farmland, soil conditions and climatic conditions. The user needs to determine the hourly water demand based on the actual working conditions.

Agricultural irrigation pumps are usually deep well pumps, which are divided into electric submersible pumps and solar submersible pumps according to the starting method.

Electric submersible pump: It is electrically driven and can provide high lift and large flow. It is suitable for extracting water from deep wells or groundwater sources. It is automatically or semi-automatically controlled by the control system. It is easy to operate and maintain.

Solar submersible pump: It is powered by solar panels and uses sunlight as energy. This means that it does not rely on the power grid and can effectively save electricity costs. It is particularly suitable for remote areas or places without power supply. It uses renewable energy, zero emissions, and no noise. It is a clean green energy solution. It is also very suitable for environmental protection projects or places with high environmental requirements. But at the same time, users also need to prepare solar panels with the required power in advance. In African countries, solar pumps are more popular.

Electric deep well pumps are more suitable for scenarios that require strong power, high continuity, and large flow, such as urban water supply, large-scale agricultural irrigation, and industrial use.
Solar submersible pumps have obvious advantages in remote areas or scenarios where electricity is scarce, especially for environmentally friendly projects such as small and medium-sized irrigation and rural water supply.

In construction projects, water pumps are widely used in water supply systems, drainage systems, fire protection systems, etc. They can provide sufficient water pressure to ensure the normal operation of buildings. At present, in the market of high-rise building booster water supply, horizontal multistage pumps with large flow and high lift have been eliminated due to their working efficiency. The light vertical multistage stainless steel booster pumps that have replaced them have become popular. However, for economical and affordable purposes, horizontal pumps are also a good choice under certain conditions. In terms of selection, horizontal multistage stainless steel pumps can be considered for the use of small flow and low lift; vertical single-stage pumps can be considered for the use of small and medium flow and low lift; vertical multistage centrifugal pumps can be considered for the use of large flow and high lift; and multiple pumps are recommended to work in parallel for the use of larger flow or heavier workload, which are usually used for the overall water supply of residential areas, water treatment in large public places such as office buildings, shopping malls, etc. And vertical multistage centrifugal pumps are also widely used in fire protection systems.

Of course, for household water treatment needs, in addition to light horizontal pumps and booster pumps, more intelligent permanent magnet variable frequency pumps are also being chosen by more and more families. With permanent magnet motors as power and smart chips as control systems, while completing the work of conventional booster pumps, permanent magnet variable frequency pumps have a smaller size and simpler installation method, and can also bring a smarter user experience.

The application of water pumps in the transportation system is mainly reflected in the fields of rivers, ports and ships. Usually including: seawater pumps, fresh water pumps, sewage pumps, sewage lifters, fuel pumps, bilge pumps, hot water circulation pumps, mud pumps and other types. Water pumps can be used to remove sludge and silt in rivers and ports to keep the waterways unobstructed; at the same time, water pumps in ships are also key equipment for the normal operation of ships. It can be used for fresh water and seawater transportation, cooling systems and ballast systems on ships. There are also some models of marine water pumps that can be used on offshore platforms to provide important transportation capabilities for offshore oil drilling platforms, such as seawater injection and drainage.

In terms of selection, users should make comprehensive choices based on the purpose of use and the water depth, water quality and drainage requirements of the target area. If you want to improve water quality, it is recommended to choose a high-efficiency clean water pump; if it is used for drainage and flood control, it is recommended to give priority to pumps with large flow and large lift; if you want to clean up garbage and filter sediment, it is recommended to choose a pump with a screening device.

Sewage lifting station are mainly used to treat sewage that is lower than the elevation of the drainage pipe or sewage system. They can lift sewage to higher pipes or sewage treatment facilities and are often used in buildings or areas where gravity drainage is not possible. In mobile facilities such as ships, cruise ships or offshore platforms, sewage lifts are used to treat domestic sewage inside the ship to ensure the normal operation of the ship and meet environmental emission requirements. In the discharge of sewage and rainwater in transportation facilities such as subway stations, tunnels, and public toilets in stations, sewage lifts ensure that these low-lying areas will not accumulate water and affect the normal operation of the facilities. It can also be used for toilet sewage treatment in public transportation places.

In our daily life, water pumps also have many applications. For example, water pumps in household water supply systems are used to provide household water; water pumps in swimming pools and fountains are used to keep water flowing and clean. In general, the application range of water pumps is very wide, covering all areas of our life and work.

In addition to the booster pumps and intelligent permanent magnet variable frequency pumps mentioned above, household toilet pumps and swimming pool pumps, SPA pumps, and sewage pumps are common in every household. Sewage pumps can not only handle rainwater collection and filtration, but also daily sewage.

Swimming pool pumps and SPA pumps are the core components of the swimming pool water circulation system, responsible for pumping out the pool water and cleaning it through the filtration system before transporting it back to the swimming pool. It can maintain the water quality and prevent the water quality from deteriorating; and plastic impellers are usually used, which can be used for seawater. There are conventional electric and solar swimming pool pumps to choose from, as well as intelligent variable speed models that can more intelligently control the swimming pool water circulation, and high-power swimming training models, which can simulate a variety of swimming scenes according to different power to better complete the training.
